Front right wheel bearing wore out at approx 100,000 miles in early 2013. Cost around $1000 to replace at the dealer. Made noise, and at it's worst (in my case) the ABS/brakes went goofy.

Now at 160,000 miles I believe the left one is now shot. Seeing now that the part is only around $100, it's quite annoying. Reading some of the stories here, it appears I've been fortunate I've gotten so many miles out of it.

This truck has been primarily a transportation vehicle, and sees limited towing/hauling duties.

Overall, I've been quite pleased with it's performance. Weighing my limited mechanical abilities, and the need to get this truck up and running, I'll be taking it to the independent shop that rebuilt the transmission.

At 53,877 miles, in Jan.2001, both front wheel hubs needed replacement. My local shop did the repair using genuine GM parts purchased at the nearest Chevy dealer.This month, at 66,367 miles, I had an issue with the computer not receiving a signal from the front right wheel.I took the truck to the Chevy dealer. Their mechanic said the wheel hub was bad, and needed replacement. He also looked at the left front wheel hub and said the signal from that one was dropping out at 4 MPH and should be replaced also. I had them replace the front right at a "discounted" price of $751.00. They stated that because the wheel hubs done at 53,877 miles weren't installed by them, the warranty was only 12,000 miles.I was over by 490 miles.Had they done the repair, they would be warrantied for life. How can two new wheel hubs go bad after 12,490 miles and General Motors wash their hands of this example of a poor quality part. I guess this matches their Intermediate Shaft, which also went bad again after just 2 years.

Purchased vehicle brand new in August 06. With less than 35000 miles had to have both wheel bearing assemblies replaced. Truck is four wheel drive. Truck is second vehicle and is used to pull camper. Paid the bill of over $1600 to have repair done. Called General Motors and asked for compensation. Was told they would not compensate me due to year of vehicle and mileage. Responded that major repairs should not be required with a vehicle with low mileage. Lot of lip service and to no avail. Requested a supervisor and one will "call me soon". Not happy. I believe if they built a quality vehicle i should not have to pay for repairs like this for quite some time. Will influence purchase on future vehicles. First vehicle was a Chevrolet and was hoping my last one would be too. Not certain, will be waiting until they "call me soon".

Purchased new 2006 - Replaced left wheel bearing at 20000 and right at 23000.

Also on 3rd set of front Pads/Rotors, Steering Shaft replaced, Heater replaced, Left Speed Sensor replaced, and Tires/Rims replaced all under 24000 miles. GM produces poor quality vehicles.

Update from Mar 15, 2012: Replaced right hub bearing myself at $130.00 - My first DIY auto project.

The Dealer charged me $688.00 for the left hub bearing replacement.

Detection - A small movement in a bearing assembly when tire is off the ground, a scraping noise, and at a worse case a grinding noise.

Update from Sep 8, 2012: 24,000 miles - Truck on lift for another repair - rusted through brake line and brakes failed. Body is like new but there is a high level of rust on entire undercarriage. Don't buy GM - poor quality.

If you own a 2006 Silverado and your "ABS" light comes on, start looking for a reliable facility to have your wheel bearing(s) replaced. Tell-tale signs will also include a "squeak or chirp" which will soon escalate into a "grind" and finally, to moderate or excessive seizure of the bearing (ulimately, the wheel assembly could fall off!). My vehicle had less than 60,000 miles when the left bearing failed, and the right one failed less than 3000 miles later! Both failures resulted in my calling a friend to bring a car hauler so the truck could be taken to the shop.

I have owned numerous vehicles in my lifetime, and have never had to replace a front wheel bearing until now. I have replaced and repacked many trailer bearings with parts usually totaling less $100.00 per wheel, and it is a fairly easy "do it yourself" task. If you have your new Silverado bearing "assembly" replaced at a repair shop get ready for the shock of $650.00+ per wheel! Neither of these replacements were covered under warranty. GM really has a problem here and will not even officially own up to it being defective issue.

Had front passenger wheel bearing go out at 29,000 miles and replaced, Replaced front passenger wheel bearing a second time at 42,000 miles. Found out that the replacement wheel bearing is good for 12,000 miles or 12 months. The second wheel bearing went for 13,000 and 13 months. Doesn't take a degree to figure who paid again. I'm the only driver and was told I must have hit something very hard. Yea right. I'm waiting to see if it fails again, if it makes it 11,000 or 11 months having the wheel pulled and checked to see if its going bad. Waiting

Went on vacation and while driving in rural New Mexico I began to hear a terrible sound out of front left wheel area. Got lucky and was able to limp vehicle to the exit ramp. It was the wheel bearings that had failed. I believe chevy knows about this problem because of all the complaints. This is the reason they need help from our government. There product is sub standard and they will continue to loose out to foreign manufacturers since they wont fix these items on recalls. I will never buy another chevy truck and am starting to shop for a foreign made truck to pull my camper. SHAME ON CHEVY - THEY HAVE ENGINEERED A TERRIBLE PRODUCT!!!

I had a front hub go out in my '06 4x4 Silverado. It was going to cost a small fortune to have it done at a Dealership. so I watched several on-line videos about swapping out a front hub and decided to try it my self. I picked up a Duralast brand hub at Autozone for $118. Nice price. The only special tool it took was a 34mm socket.

I popped off the lug nut cover, used a wood chisel to take off the center cap, used the 34mm socket on a breaker bar with a 4' piece of pipe for leverage to loosen up the center nut that holds the whole mess on. Do this with the car still on the ground.

Then off with the lugs, up with the truck front end and off with the tire. remove the two 18mm bolts that hold on the brakes and you are in. With a hammer and pry bar the old hub comes right off (ha) then disconnect the antilock wire connection. Follow this in reverse to put it on. It only took me about an hour to fix this laying on my back in the dirt driveway. Oh yeah it snowed that day as well. That part sucked but the rest was pretty easy as far as fixes go. I would change the other one myself if it goes to hell. I heard that if you go in deep water or deep snow the moisture gets trapped inside the back part of the wheel bearing. But since my lasted over 100k miles I am pretty happy with it. Nate - Colorado's high country

I lost my right front bearing at 26000 miles, which was covered under the warranty. I asked them at the time if there was a problem with the bearings and was told no and that this was a fluke. Now at 45000 miles I lost my left front bearing with no coverage. After $724

and two days in the shop I got my truck back. I called GM and got the typical response that there is no problem and parts wear. I do not drive this truck hard, it's basically a car with a bed. Hopefully GM will get their act together and start standing behind their product. I bought this truck thinking I was doing the right thing buying American. Well, fool me once

shame on you, fool me twice shame on me.

Coming back from a vacation over the 4th of July weekend. We were on I-40 by Newport TN. I could here a squealing/sqeaking noise. We pulled off to get gas and I had my wife listen to the truck as I pulled away from the gas pump. I was hoping it was just a noise coming from the trailer we were pulling. Not so lucky. I pulled out of the lot and could feel the steering start to bind. It was clunking and grinding really bad. I limped it down to the local Chevy dealer and we found that the left front bearing was locked up. In a really BAD way. I told them to check the right as well and we noticed that it was starting to click too. I paid $110 for my extended warranty deductible and they installed the 2 bearings, which were $493/ea. Total bill was $1200. From what I was told, American Bearing made the bearings for the 2006 model and had gone on strike during the build. The new bearing is by a new mfg and Chevy will back it for life. If it ever needs to be replaced they will pay the parts and labor. So if anyone has this issue, make sure they install the new bearing and that your paperwork reflects this. I was very glad I had purchased the ext wrty when I bought the truck new.
